Xu, Hong Zhen; Tang, Lan Fang; Zheng, Xiao Ping & Chen, Zhi Min


Objective: To analyze the clinical and radiological features of paragonimiasis in children and raise the awareness of this disease.
Methods: A total of 58 paragonimiasis patients were reviewed. They were 42 boys and 16 girls aged 2.0 to 15.3 years.
Findings: Among these patients, 20 were diagnosed in the recent 5 years, 46 with a history of raw water or food ingestion. Except 2 patients without any complaint, the most common features involved the systemic (41, 70.7%) and respiratory systems (43, 74.1%), followed by abdominal, cardiac and nervous systems, with rash and mass. Eosinophilia was noted in 46 (79.3%) patients, granulocytosis in 45 (77.6%), anemia in 14 (24.1%), and thrombocytopenia in 3. Imageology showed pneumonia in 26 (44.8%) patients, pleurisy in 28 (48.3%), hydropericardium in 17 (29.3%), ascites in 16 (27.6%), and celiac lymphadenitis in 13 (22.4%). Besides hepatomegaly and splenomegaly, calcification and multiple lamellar low echogenic areas in the liver were noted, each in one patient. Abnormal brain imaging was noted in 4 of 10 patients. Karyocyte hyperplasia with eosinophilia was noted in all the 19 patients who received bone marrow puncture.
Conclusion:Paragonimiasis should be considered in the differential diagnosis of patients withmultiple organs or system lesions, especially those with eosinophilia, serous cavity effusion, respiratory, cardiac, digestive system, nervous system abnormality, and/or mass. Healthy eating habit is helpful for paragonimiasis prevention.
